DEVICE FOR DISPENSING PULVERIZED MATERIALS FROM CONTAINER Filed March 6', 1956 INVENTORS BERNARD MENCHEN WALTER DEEN FINNEY ATTORNEYS United States Patent DEVICE FOR DISPENSING PULVERIZED MATERIALS FROM CONTAINER Bernard Menchen and Walter Deen Finney, Los Angeles, Calif.

Application March 6, 1956, Serial No. 569,996

1 Claim. (Cl. 222--81) This invention has to do with dispensers, and relates more particularly to devices for dispensing pulverized material from relatively large containers.

Many pulverized materials, such as plastics, are sold in bulk in large cardboard containers and the purchasers only use small amounts of the material from time to time, which requires burdensome handling of the large container and considerable waste. While it has been proposed to provide dispensers in the form of pouring spouts which pierce the container and thus provide a pouring spout through which material may be poured, those have not been satisfactory because, to use them, still requires that the relatively large container be lifted and handled in order to effect the pouring.

It is therefore an object of our invention to provide a dispenser which incorporates not only a container-piercing portion to be inserted through the wall of a large container, but also incorporates a convenient receptacle portion accessible through an opening normally covered by a swingable lid.

Other objects and advantages will appear hereinafter.

While we shall point out in the appended claim the features which we believe to be new, for the purpose of explaining our invention we shall now describe a presently preferred embodiment thereof, for which purpose we shall refer to the accompanying drawing wherein,

Fig. 1 is a side elevation, with parts broken away for illustrative purposes, showing our dispenser mounted on a relatively large container;

Fig. 2 is a top plan view of our dispensing device;

Fig. 3 is a front end elevation thereof; and

Fig. 4 is an enlarged section taken on line 44 of Fig. 2.

Referring now to the drawing, we show (Fig. 1) a conventional container C whose side walls C are preferably made of cardboard which may be easily pierced. Powdered material M is contained within the container. Our dispensing device is generally denoted by the numeral 1.

The dispenser 1 comprises a hollow body 5 having a front portion 6 and a rear portion 7. The rear portion comprises a flat bottom wall 15 having a diagonally disposed outer end edge 17 which is preferably beveled to render it relatively sharp, and parallel upright side walls 18, 19 whose sloped outer end edge portions are preferably beveled at 21 to provide them with cutting edges. The outer end edge 17 of the bottom wall 15 intersects the side wall 19 in a sharp point 20.

The front, or material receptacle portion 6 comprises a flat bottom wall 25, parallel upright side walls 26, an upright front wall 27 and a top wall 28.

The top edge portions of the side walls 26 slope downwardly from the top wall to the relatively low front wall 27 to provide a diagonally upward access opening 29 and "ice a cover lid 30 for said opening is secured to the top wall by a hinge 31, the cover lid being provided with depending side flanges 33 which ride over the top edge portions of the side walls. Preferably also the cover lid is provided with laterally projecting ears 34, one on each side, to provide finger-gripping members for use in raising the cover lid.

The top wall 28 may be secured to the side walls 26 by having depending end portions 28a secured to the side walls as by spot welds 35 or in any other suitable manner.

Each of the side walls has its inner end edge portion turned outwardly to provide a flange 37 for engaging the outer surface of the container C, while the top wall 28 has its inner end edge portion upturned to provide a flange 38 in the plane of flanges 37 and for the same purpose. The side walls 18, 19 and the bottom wall 15 of the rear portion 7 have their inner end marginal portions secured to the side and bottom walls of the front portion as by spot welds 39.

Since the device is hollow it will be apparent that the front and rear portions 6 and 7 are in communication with each other.

In use, the pointed rear portion of the device is forced through the side wall of the container C until the flanges 37, 38 engage the outer surface of the container, after which the pulverized material M in the container flows into the receptacle provided by the front portion 6 of the device. To remove material from the receptacle, it is only necessary to lift the cover lid 30 and dip material out of the receptacle through opening 29, the receptacle becoming automatically reloaded by gravity flow from the container as material is removed from the receptacle. Since the side wall of the container is only pierced to the height of the side walls 18, 19 of the rear portion, which are of less height than the side walls of the front por-' tion and since the top of the receptacle adjacent the container is therefore above the plane of the top edges of the side walls of the rear portion, there is normally a space above the material in the receptacle which prevents packing in the receptacle and insures easy flow into the receptacle from the container.

We claim:

In a dispensing device for piercing a side wall of an upright container of pulverized material, a hollow body having a front portion and a rear portion, said front portion having a horizontal bottom wall, upright side walls, an upright front wall and a top wall defining a diagonally upwardly opening material receptacle, the inner edge portion of said side and top walls having lateral flanges disposed to engage the outer surface of said container, and a receptacle cover hingedly connected to said top wall, and said rear portion comprising a horizontal bottom wall having a container-piercing pointed outer edge portion and parallel side walls having sloped relatively sharp container cutting top edge portions; said rear portion defining a horizontally disposed material passageway of a depth less than the major depth of said receptacle and communicating with said receptacle whereby when said rear portion is within said container the material will flow into said receptacle without the necessity of tilting said container.
